Collection of information
(Database Management System) refers to software that is designed to manage data stored in a database.
Responsible for data from more than one database

Changes and does not
GoTo vs. GoSub
- is a statement found in many computer programming languages. It is a combination of the English words goand to. It performs a one-way transfer of control to another line of code; in contrast a function call normally returns control. The jumped-to locations are usually identified using labels, though some languages use line numbers. At the machine code level, a goto is a form of branch or jump statement.
- is a command in many versions of the BASIC computer programming language. A GOSUB statement jumps to a line elsewhere in the program. That line and the following lines up to a RETURN are used as a simple kind of a subroutine without (sometimes with) parameters or local variables.
